During the expected float service life of GFM batteries, no need to check the specific gravity of the electrolyte or add water. Good Discharging AbilityTight assembly technology ensures an excellent high-rate discharge performance. Long Service LifeA unique corrosion-resistant grid alloy ensures GFM batteries have long service life. Low Self Discharge Using high purity raw materials ensures GFM batteries have less self-discharge. Environmental & Non-polluting Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out. Safe & Reliable Efficient venting system automatically release excess gas when the pressure rises above the normal level & reseals the valves when it returns to the normal rate, which can protect the battery from bursting. Notice: Don’t near the hot source and don’t under the sunshine.Don’t charge in the sealed container.No short circuit. It should be addition charge if you don’t use, and single charge per three months, to avoid irreversible sulfating. The battery should be changed when the battery jar broken or the electrolyte omitted, to avoid acid corrosion.Don’t store in the space of acid gas.You should be careful and regular check when use the battery. To avoid the battery don’t work. You should change the battery if the capacity is not full or has been damage, especially after one year using.Don’t put the battery in the fire, or it will explode.Please use cotton cloth to clean, if the battery is broken down and leak electrolyte. Please wash your skin when touch the electrolyte.Don’t clean the battery by using the organic solution.
